In December, 2024, I rolled over my traditional 401K to my brokerage IRA accounts. Since I have both before tax contribution and after contribution in my 401K, so the 401K administrator wired two separate rollover transactions, one to my regular IRA and the other one to my ROTH IRA.
I discovered immediately that they rolled over the before tax earning from the after-tax contribution to ROTH as well, so I requested the brokerage firm to correct the rollover error as the 401K administrator stated they will not able to do since it was wired. From the brokerage perspective, none of them are taxable events. However, on my 1099-R, the earning of the after-tax contribution is taxable. When I contacted my 401K administrator, they will not make a change on 1099-R because they said they do not know what happened after the rollover. Please advise what is the proper way to report this on my 2024 tax. Thank you.
